TECHNICAL FIELD

This disclosure relates to thermally insulated containers for liquids, and more specifically to thermally insulated caps for such thermally insulated containers.

INTRODUCTION

When a need exists to store or transport a substance, and it is furthermore desirable to keep that substance at temperature that is either higher or lower than ambient temperature, the solution is typically an insulated container. Insulated containers are available in a vast number of configurations depending upon the substance to be transported and the temperatures to be maintained, from the thermal bags used to deliver hot pizzas to the cryogenic storage dewars used to hold cryogens such as liquefied gases.

Of particular utility are beverage containers, such as water bottles or sports bottles, that are typically used to contain beverages that are either colder (such as ice water) or hotter (such as coffee) than ambient temperatures. To maintain such beverages at their desired temperature for a desired amount of time, such containers typically contain insulating structures and/or materials.

DESCRIPTION

The present disclosure may illustrate and describe a number of insulated caps in the present drawings and specification. Unless otherwise specified, the insulated cap and/or its various components may, but are not required to, contain at least one of the structure, components, functionality, and/or variations described, illustrated, and/or incorporated herein. Furthermore, the process steps, structures, components, functionalities, and/or variations described, illustrated, and/or incorporated herein in connection with the present teachings may, but are not required to, be included in other similar insulated caps. The following description is merely exemplary and is in no way intended to limit the disclosure, its application, or uses. Additionally, the advantages provided by the embodiments, as described below, are illustrative and not all embodiments provide the same advantages or the same degree of advantages.

FIG. 1 depicts an illustrative insulated container assembly 10 that includes an insulated container 12 and an insulated cap 14 that is complementary to the insulated container 12. The insulated cap 14 and insulated container 12 are depicted in a partially exploded view for clarity. The insulated cap 14 may be configured to be removably attachable to the associated thermally insulated container 12. The underside of insulated cap 14 is shown in FIG. 2.

The insulated container 12 may be configured to retain a desired substance, and in particular may be configured to retain the desired substance at a temperature that is either higher or lower than an ambient temperature. In one aspect of the disclosure, the insulated container 12 is configured to be used as a beverage container, and may correspond to or resemble a bottle, jug, growler, vessel, carafe, or similar beverage container. Insulated container 12 may be fashioned from any material having the desired properties for a beverage container, such as a stainless steel or a plastic formulation. The insulated container 12 may incorporate any of a variety of insulating materials, or combination of insulating materials, so as to limit the transfer of heat through the walls of the container. In one aspect of the disclosure, the insulated container 12 may incorporate a double-walled construction, with the intervening space between the walls being substantially evacuated, so that the container is a vacuum-insulated Insulated container 12 may include any suitable container configured to portably contain liquids. For example, insulated container 12 may include a bottle, jug, growler, vessel, carafe, or the like. The insulated container 12 may include a stainless steel In one aspect of the disclosure the container is fashioned from stainless steel, incorporates a double-walled construction, and is vacuum-insulated. Examples of appropriate vacuum-insulated stainless steel beverage containers for the purposes of present disclosure may be commercially available from HYDRO FLASK (Bend,

The insulated container 12 may include a mouth portion 16 that provides access to an interior 18 of the insulated container 12. In some aspects, the insulated container 12 may include a mouth portion 16 that forms an opening at the distal portion of a neck 20 of the insulated container 12. The upper portion of the insulated container 12 may be defined as that portion of the insulated container 12 that includes the neck 20 and mouth portion 16 of the insulated container, consistent with the conventional and common usage when describing a container for liquids.

As may be more clearly shown in FIG. 2, the portion of the insulated cap 14 that may be configured to make contact with the mouth potion 16 and to face the interior 18 of the insulated container 12 may be referred to as the interior portion 22, or inner portion, or lower portion of the insulated cap 14, without limitation. Similarly, the surface of the insulated cap 14 that faces the interior 18 of the insulated container 12 may be referred to as an inner surface 24 of the insulated cap 14.

The portion of the insulated cap 14 that may be disposed opposite the interior portion 22 may be referred to as the exterior portion 26, the upper portion, or the outer portion of the insulated cap 14, without limitation. Similarly, the surface of the insulated cap 14 disposed opposite the inner surface 24 of the insulated cap may be referred to as the outer surface 27 of the insulated cap 14, the upper surface of the insulated cap, or the exterior surface of the insulated cap, without limitation.

The insulated cap 14 (which may alternatively be referred to as a lid) may include one or more suitable structures and components configured so as to provide a sealing closure for mouth 16 of insulated container 12. The insulated cap 14 may a first securing element 30 that is configured to secure the insulated cap 14 to the insulated container 12, such that when the insulated cap 14 is secured by securing element 30, the container assembly 10 is substantially airtight, and the contents of the container assembly 10 are substantially not prone to leaking during routine handling and/or transport. The first securing element 30 may be configured to be complementary to, and to cooperate with, a second securing element 32 disposed on or coupled to the insulated container 12.

For example, and with reference to FIG. 1, the insulated cap 14 may include a first securing element 30 that corresponds to a threading 34 that is complementary to a second securing element 32 that may include a threading 36 disposed on or adjacent to the mouth portion 16 or neck 20 of the insulated container 12. That is, threading 34 of the insulated cap 14 may be configured to mate with threading 36 of the insulated container 12, so that the insulated cap 14 may be secured to the neck 20 and thereby secured to and against mouth portion 16.

As shown in FIG. 1, for those aspects of the disclosure where the first and second securing elements may include complementary threading, the threading 36 on the insulated container 12 may be disposed on an outer surface 38 of the neck (e.g., exterior portion 26) of the insulated container 12, and the corresponding complementary threading 34 may be disposed on an inner surface 40 of a circumferential sidewall 42 of the insulated cap 14, so that threading 34 and threading 36 may positively interact to secure the insulated cap 14 to the insulated container 12.

However, it should be appreciated that in an alternative aspect of the disclosure, the insulated container 12 may include threading 36 disposed on an inner surface of the neck 20 of the insulated container 12. In this instance, as shown in FIG. 3, the complementary cap threading 34 may be disposed on a projecting interior portion 22 of the insulating cap 14 that may be configured to be inserted at least partially into the neck 20 of the insulated container 12, such that threading 34 and threading 36 may positively interact to secure the insulated cap 14 to the insulated container 12.

Although insulated beverage containers having threaded couplings to their lids described herein, it should be readily apparent that a variety of additional and/or alternative configurations and conformations of securing elements may be utilized in the container assemblies of the present disclosure, and any alternative securing element or pair of securing elements that serve to secures the insulated cap 14 against the container 12 and to create a substantially airtight seal may be an appropriate securing element or elements for the purposes of this disclosure. For example, the insulated cap 14 may be retained by a securing element that includes a swing-top closure, where the insulated cap 14 may be retained by a wire bail configured so that in a first position the insulated cap 14 is retained in place against the mouth portion 16 of the insulated container 12, and a second position where the insulated cap 14 is released from contact with the insulated container 12, but the cap 14 remains connected to the container 12 the wire bail. The wire bail may be configured so that the wire bail may be manually from the first position to the second position, thereby opening the container assembly

The insulated cap 14 (also referred to as a lid) may include any suitable structures and components configured to provide an insulated, releasable sealing closure for mouth 16 of insulated container 12. As shown in FIGS. 4-6, an illustrative insulated cap 14 according to the present disclosure may include an outer shell 44, an insulation block 46, and a sealing member 48. Additionally, or in the alternative, the insulated cap 14 may include a handle or carrying strap 50.

Outer shell 44 may include any suitable structure configured to provide an outer cap, shell, or housing for insulated cap 14, and may further include a grippable and/or manipulable surface configured to assist in attaching and/or detaching the insulated cap 14 from the insulated container 12. The outer shell 44 may incorporate one or more contours and/or portions or regions of texture. Alternatively, or in addition, the outer shell 44 may be molded or inscribed to provide an aesthetic, instructional, or functional interface for a user of the insulated container assembly 10. Outer shell 44 may include any suitable material having sufficient structural strength and rigidity to form the outer shell. For example, outer shell 44 may include a plastic, such as a thermoplastic, or a thermosetting polymer. In one aspect of the disclosure, the outer shell 44 incorporates a thermoplastic that is a polypropylene polymer.

In addition to structures and features disposed on an exterior surface 52 of outer shell 44, the outer shell of insulated cap 14 may also include one or more features on an interior surface that are configured to interact with one or more features of the insulated cap. For example, outer shell 44 may define apertures or through-holes that may be configured to facilitate the attachment of a carrying strap 50, and/or contours and features disposed on or formed in an inner surface 54 of the outer shell 44 that are configured to interface with insulation block 46.

Insulation block 46 may be mated with, attached to, or unitary with the inner surface 54 of outer shell 44, such that outer shell 44 substantially covers both the upper and lateral surfaces of the insulation block 46. Insulation block 46 may include any suitable insulating material or insulating structure configured to enhance the thermal insulating properties of the insulating cap 14. That is, to reduce the rate of heat transfer between the lower or inner surface 24 of the insulated cap and the upper or outer 28 of the insulated cap 14. In other words, insulation block 46 may be configured to function as a thermal barrier to heat transfer between the interior and the exterior of the insulated container 12.

Insulation block 46 may incorporate any suitable material, structure, or device configured to reduce heat transfer between the upper and lower surfaces (or the outer and inner surfaces) of the insulation block 46. For example, for example, insulation block 46 may include one or more materials that have inherently low heat transfer characteristics. In addition to having advantageous thermal properties, the materials making up insulation block 46 may be selected based upon their mechanical properties, such as being easy to form and/or machine. For example, insulation block 46 may comprise one or more plastics, such as thermosetting polymers, thermoplastics, or other polymer formulations. The insulation block 46 may include one or more plastics that may be the same or different than the plastics used for forming outer shell 44. In a selected aspect of the disclosure, the insulation block 46 may be formed from polypropylene polymer.

In addition to the incorporation of an insulating material, the insulation block 46 may be formed into a structure or shape that itself enhances the thermal insulating properties of the insulation block 46. For example, insulation block 46 may include a plurality of internal voids or apertures 56 configured so that the spaces formed by the voids 56 decrease the thermal transfer due to conduction through the material of the insulation block 46. The voids 56 may take the form of a plurality of closed cells, a of open cells, or a combination thereof. The insulation block 46 may be configured so one or more of voids 56 are filled with air, and the resulting plurality of air-spaces the insulating qualities of the insulation block 46. Alternatively, or in addition, one or of voids 56 may be filled with a gas, such as for example nitrogen, carbon dioxide, among others. In yet another aspect of the insulation block 46, one or more of voids 56 may be evacuated, so that the resulting evacuated spaces enhance the thermal insulating properties of insulation block 46.

Any appropriate number and arrangement of voids or apertures 56 may be formed in insulation block 46. In one aspect of the disclosure, the voids or apertures 56 are defined so that they are elongate voids. That is, the void extends further in one dimension than in any other dimension. Where one or more voids 56 are elongate voids, the voids may be deemed to possess a longitudinal axis.

The insulation block 46 may incorporate a plurality of elongate voids 56 that are formed so that the longitudinal axes of each of the elongate voids are substantially parallel to one another. In other words, the elongate voids 56 may be disposed so that they are substantially aligned with one another. The elongate voids 56 may be formed in insulation block 46 so that their longitudinal axes extend vertically, that is, the longitudinal axes extend between the upper and exterior portion 26 of the insulated cap 14 and the lower or interior portion 22 of the insulated cap 14.

The elongate voids may be formed in any shape or geometry that may be suitable, and that may enhance the thermal insulation of the insulated cap 14. In a selected aspect of the disclosure, each of the elongate voids has a polygonal cross-section, where the cross-section is taken at right angles to the longitudinal axis of the void, such that each includes an elongate polygonal columnar void. For example, each of the elongate voids may have a cross-section that defines a hexagon. Where the elongate voids have a hexagonal cross-section, it may be advantageous for the hexagonal voids to be formed in a close-packed array, as shown in FIG. 5, thereby forming a honeycomb pattern. This construction may minimize the amount of material needed to form the insulation block 46, as well is reducing the loss of heat through the insulation block 46 through direct conduction.

Although the voids formed in the insulation block 46 may be completely enclosed, in one aspect of the disclosure it may be advantageous to form the elongate voids 56 by forming a plurality of open-ended apertures in the upper face 58 of insulation block 46. In this way, placing the insulation block 46 within the outer shell 44 serves to cap or seal the apertures, as shown most clearly in FIGS. 4 and 5.

Insulation block 46 may be formed from any suitably non-toxic material that is substantially taste-neutral. In other words, although some materials may impart a flavor liquids they contact, a taste-neutral material does not, or does so to a much lower Where insulation block 46 is formed from a non-toxic and taste-neutral material, the or inner surface of the insulation block 46 may also serve as the lower or inner face of insulated cap 14.

Alternatively, the insulated cap 14 may further include an inner liner 62 configured to substantially isolate the interior volume of the insulated container 12 from the insulation block 46 when the insulated cap 14 is coupled to the insulated container 12, as shown in FIGS. 4 and 6. The inner liner 62 may also be non-toxic and substantially taste-neutral. Suitable inner liners 62 may be formed from, for example, stainless steel, or silicone, among others.

Where insulated cap 14 includes an inner liner 62, the inner liner may include a continuous capping structure configured to partially encase the insulation block 46, as shown in FIG. 4. In one aspect of the disclosure, the inner liner 62 may include a cap or cup that interfaces with insulation block 46 and/or outer shell 44 at an upper end of the liner 62, thereby forming a narrow annular channel into which the walls of the neck 20 of insulated container 12 may be inserted. In this way, the interior of the insulated container 12, and therefore the contents of insulated container 12, is exposed only to the inner liner 62, while the exterior of the insulated container 12 (e.g., threading 36) may contact outer shell 44 and/or insulation block 46.

The isolation of the insulation block 46 and outer shell 44 from the interior 18 of insulated container 12 may be further facilitated by the presence of sealing member 48. Sealing member 48 may include any material or structure that creates or enhances an air-tight seal between the insulated cap 14 and insulated container 12, such as a seal, a ring, a gasket, or O-ring. Although a variety of suitable shapes may be useful as a sealing member, in one aspect of the disclosure the suitable sealing member 48 may include a resilient O-ring, which may incorporate a tubular ring or solid ring having a circular cross section. The O-ring may include a silicone rubber.

The insulated cap 14 may further include a handle that is configured to facilitate carrying the insulated container assembly 10. Although any type of handle may be used to carry the insulated container assembly, it may be particularly convenient to employ a handle that includes a loop or carrying strap 50, as shown in FIGS. 1-6. Carrying strap may be coupled to the insulated cap 14 with a pivotable or a non-pivotable connection, and may include any suitable material or strap configuration adequate to support the weight of the assembled container assembly 10 when filled with a liquid. In one aspect the disclosure, carrying strap 50 may include a flat strap. Carrying strap 50 may include flexible, compliant, and/or resilient material, such as for example a flexible plastic, or silicone rubber material. The carrying strap 50 may be a single ply of material, or may incorporate one or more layers of material bound in a stack.

In one aspect of the disclosure, carrying strap 50 is pivotally connected to the outer shell 44 of the insulated cap 14, and optionally further connected to the insulation block 46 within the outer shell 44, via two pins 66. Pins 66 may be attached to the insulated cap 14 by any suitable method, such as being press-fit into appropriate apertures formed in the outer shell 44. Such apertures may include a raised boss or protrusion. Alternatively, or in addition, pins 66 may be fixed by being overmolded during manufacture of the insulated cap 14. The pins 66 may include any suitable material, such as rigid or resilient plastic or rubber, or stainless steel.

Carrying strap 50 may be attached relatively permanently, or may be configured so that it can be removed and/or replaced, either to repair the carrying strap or to change the colors or appearance of the container assembly. The outer shell 44 and/or pins 66 may include contours or other features that may function as detent mechanisms to releasably retain strap 50 in a desired orientation with respect to insulated cap 14. The insulated caps of the present disclosure may be manufactured as set out in flowchart 70 of FIG. 7, which includes forming an insulation block that defines a plurality of voids formed in its upper surface, at 72; forming an outer shell configured to form an outer surface of an insulating cap, at 74; and coupling the insulation block with the outer shell so that the outer shell caps the plurality of voids in the insulation block, at 76. The insulated caps 14 of the disclosure may be prepared via any suitable manufacturing method, including but not limited to spin-welding and/or over-molding processes.
